Sad news... AfriGIS have locked down the live API feed of Gautrain bus positions. Very sad these guys are so closed minded.
Quick Investigation
-------------------
GET https://mobilemaps.afrigis.co.za/ashx/GetCommonSettings.ashx?Application=GAUTRAIN_ANDROID&MajorVersion=1.6.2&RType=json
	Provides link to SAAS

Bus API has moved to: https://saas.afrigis.co.za/
Uses a uniquely generated URL per query (url encodes a timestamp)

eg: https://saas.afrigis.co.za/rest/2/gautrain.mobileServer.getBusesByBoundingBoxServlet/{EncodingVersion}/{AuthCode}/{UnixTimeStamp}/?east=28.212890625&south=-26.0595703125&north=-25.90576171875&west=28.0810546875

EncodingVersion = static hash
AuthCode = Hash of API call type (gautrain.mobileServer.getBusesByBoundingBoxServlet), Query Params (east=, west=...), UnixTimeStamp, EncodingVersion & SecretKey
UnixTimeStamp = Unix Time Stamp in UTC

UPDATE:
Cracked it... email me for details

UPDATE: 29th August 2014 - 09:00 SAST
Has stopped working again... Will investigate when I get a chance.

UPDATE: 6th September 2014
Working again. Simple URL change

UPDATE: October 2017
Secret key changed and server time offset "obfustication"
